Java HotSpot Virtual Machine

Hi,

We are running a standard J2EE application on JBoss. The app is running on half a dozen different machines, all Windows but different versions (XP SP2, W2K and Server 2003). All machines are running Java 1.4.2 (build 1.4.2-b28) in Server mode.

Every month or so we find that Windows reports an error with the java.exe, the message as follows:

Faulting application JavaService.exe, version 1.1.0.0,
faulting module jvm.dll, version 0.0.0.0, fault address 0x000ab67b

Interestingly, if this occurs while the app is running in the console on XP, we get the "Java.exe has encountered an error.... send report." style dialog box, but the app continues seemingly without problem until the dialog is acknowledged, at which point the whole thing disappears ("press any key to continue" message in the console). If the app is running as a service, then java stops immediately with the same message. The message is the same on all machines.

I've sure we or our third party suppliers don't make use of any JNI, so I've discounted that as the cause. Nor do we do anything fancy with JVM switches, only setting the -Xmx switch to between 500-1400 depending on the machine. The problem has occurred at both extremes of this range.

I wonder if anyone has seen something like this? I've searched the forums and found a few crashing jvms with seg faults. This seems to be happening 1.4.2; is there a issue with some builds?

Any comments much appreciated.

Thanks, Alex.
